IELTS

GRE is not mandatory. IELTS must be taken by all international applicants, even if you have German language knowledge.

The universities does not require any other tests. GMAT or GRE are usually for the top ones, so if you want to get into an average college, you may have a chance. You can also check popular colleges under SPP.
Some of the decent options could be:
1. Vancouver Island University.
2. Thomson River Univers

Hi,
A good band score (say 7) will get you into countries like UK, Australia and Canada. There are tons of universities in Europe that accept IELTS for selection. However, you might want to check the university website if your preferred course is available in English. Take language proficiency tests

Canada is a better country but try to get 7 bands so as to become safe.

According to me, there is no criteria except you must be above 18 years of age. Kindly, check ielts.prg website, create an account, pay the fee and schedule your test. There are certain rules for cancelation and rescheduling.

Hi Jay,
This is a difficult question to answer. There are thousands of universities abroad and also you must be more specific about the country choice as to the university which will give you the admission will entirely depend on your overall application profile and the university's selection proces

To get 6.5 bands in IELTS is not difficult at all. You just have to be familiar with the exam pattern and a practice of 1 to 2 months is enough to crack IELTS paper.
Moreover, keep in mind that IELTS is widely accepted in all European countries, while TOEFL is favoured by USA and UK.

No, you need to take GRE and for automotive systems, I would suggest to try German Universities. You can check their websites.
